Regex101

In this blog post, we will try to tell our users what the term regex101 actually means. The term regex actually means the regular expression. String character combinations can be matched using regular expressions, which are patterns.

Regular expressions are also objects in JavaScript. In addition to the match(), matchAll(), replace(), replaceAll(), search(), and split() methods of String, these patterns can be utilised with the exec() and test() methods of RegExp.

You can debug your regular expressions in real-time using the interactive regular expression console on Regex101.com. This implies that you may create your expressions and watch how they impact a real data set all on the same screen. Firas Dib developed the tool with assistance from numerous other programmers.

Even when a regex is used with the g modifier, RegExp#exec() only returns a single match object. To obtain all match values, combine a regex with the g modifier and use String#match: 

var match: string[] = 'christiancattano'.match(regExObj)

We can quickly create expressions on Regex101.com and debug them as we go. A set of data may be pasted in, and after some trial and error, we can create an expression that performs the desired action.

The tool clearly indicates whether or not the data matches our expression. A screenshot of the same is also shown here:
